ANDREW J. BLAOKMAN, OF MERIDIAN, MISSISSIPPI.

CHURN-DASHER.

SPECIFICATION forming'part of Letters Patent No. 266,011, dated October17, 1882.

Application filed March 6, 188-2. (N 0 model.)

To all whom it may concern Be it known that I, A. J. BLACKMAN, ofMeridian, in the county of Lauderdale and State of Mississippi, haveinvented certain new and useful Improvements in ()hurn-Dashers; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanyingdrawings, which form a part of this specification.

Figure 1 is a perspective view of my improved churn-dasher, and Fig. 2is a transverse sectional view of the same.

Similar letters of reference indicate corresponding parts in bothfigures.

This invention relates to dashers for rotary churns; and it consists inthe improved construction of the same, which will be hereinafter fullydescribed, and particularly pointed out in the claim.

In the drawings hereto annexed, A represents the shaft of my improveddasher, which is provided with journals B B, by which it may be mountedin suitable hearings in the churnhody. The shaft A extends at G beyondthe journal B, in order that a crank or other means for imparting motionmay be attached thereto. The shaftA is provided with radiating arms orheaters I), placed closely together over the entirelength of the shalt,and projecting from the four sides of the shaft at right angles to eachother. Mounted upon each of the four sets of arms or heaters,which areall of equal length, so as to extend nearly to the sides of thechurnhody, is a longitudinal cutter-bar, E, which is fl-at,as showmandprovided on both sides with sharp edges F. The cutter-hars E haveperforations G registering with the arms D, to enable them to be mountedupon said arms,where v the said cutter-bars are placed at unequaldistances from the central shaft-thus, one at the outer ends of thebeaters,one between the middle and the outer ends, one near the middle,and the fourth near the shaft. The cutter-bars may be retained in theirproper positions by means of flanges Hand nuts I upon two or more ofeach set of heaters, or in any other suitable manner.

By the peculiar arrangement of the cutterhars, as herein described, theentire body of cream which is whipped by the arms or beat ers D isthoroughly out and stirred, thus enabling me to manufacture butter bythe use of my improved dasher in a very short time. The dotted lines inFig. 2 show how the cutterha rs move in four different courses,whileFig. 1. illustrates how the heaters, being arranged over. the entirelength of the shaft, will serve to agitate the entire body of cream, nomatter whether the churn he filled or only partly full. The constructionis simple, and the dasher may be manufactured at a small expense.

I am aware that a rotary shaft having radial arms on which cutter-barsare arranged, and rotary shafts having cutters at unequal distances fromthe shaft, are old, and such I do not claim as my invention.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States In a rotary churn-dasher, thecombination, with the central rotary shaft, A, having radial heaters Darranged in four sets or series, havin g the heaters arranged one abovethe other, and the heaters of one set adapted to correspond, when theshaft revolves, to the space between the heaters of the adjoining sets,said heaters being all of the same length and extending nearly to thesides of the churn, of the vertical heaters or cutters havingperforations G, by which they are adjusted, one on each set of heatersD, parallel to the shaft, and arranged, one on the extreme ends of thebeaters of its series D, the next near the center of the heaters, thenext at the center, and the next near the shaft, so that the cutterseach operate in a different circular course, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

ANDREW JUDSON BMCKMAN.
